How do I know the order in which hooks are showing up in execution?

I would like to, for example, add a function to a hook that shows up right after "the_content" gets fired and I cannot find anything on this topic anywhere, can anyone help?

Is the order in which hooks show up in $wp_filter the same order in which they get executed?

Thanks!

You can checkout: https://wordpress.org/plugins/query-monitor/screenshots/

Also 

<?php //LIST ALL HOOKS

  function dump_hook( $tag, $hook ) {
      ksort($hook);

      echo "<pre>>>>>>\t$tag<br>";

      foreach( $hook as $priority => $functions ) {

      echo $priority;

      foreach( $functions as $function )
          if( $function['function'] != 'list_hook_details' ) {

          echo "\t";

          if( is_string( $function['function'] ) )
              echo $function['function'];

          elseif( is_string( $function['function'][0] ) )
               echo $function['function'][0] . ' -> ' . $function['function'][1];

          elseif( is_object( $function['function'][0] ) )
              echo "(object) " . get_class( $function['function'][0] ) . ' -> ' . $function['function'][1];

          else
              print_r($function);

          echo ' (' . $function['accepted_args'] . ') <br>';
          }
      }

      echo '</pre>';
  }

  function list_hooks( $filter = false ){
      global $wp_filter;

      $hooks = $wp_filter;
      ksort( $hooks );

      foreach( $hooks as $tag => $hook )
          if ( false === $filter || false !== strpos( $tag, $filter ) )
              dump_hook($tag, $hook);
  }

?>

and then call it

<?php list_hooks(); ?>

You mainly want to look into priority paramater and change it to fit your needs.
